Relocating secondary SAN
We are looking at moving our DR site and so the SAN would be down for several days. Are there any concerns with RecoverPoint? Anything special we need to do in shutting down the DR side? The IP range is moving with the equipment, so no changes will be made.

You will obviously have no replication. Since RecoverPoint does not "know" whether any writes were missed at DR during the move, it will perform a full sweep.
Before shutting down RecoverPoint, enable image access on the most recent image and then disable all CG. It would guarantee that you have a last good/consistent image at the DR before the move.
Gracefully shut down RPAs by detaching them from the cluster and then shutting down from boxmgmt menu.
When RPAs come up, you have a CG option to disable fast initialization. If you do, it will preserve the last good/consistent image at DR while RP performs a full sweep (provided you have enough journal space for the delta accumulated while replication was down). If, instead, you prefer the full sweep to complete faster, leave fast initialization on.
